Human Physiology: Body Fluids and Circulation for Beginners

Understanding how our bodies transport nutrients, oxygen, and waste is fundamental to mastering human biology. This text-based course breaks down the complex systems of body fluids and circulation into clear, readable, and digestible concepts. By the end of this course, you will transition from having a basic awareness of heart health to deeply understanding the cellular makeup of blood, the mechanics of the cardiac cycle, and the pathways of systemic and pulmonary circulation. What you'll learn: - Understand the detailed composition of blood, including plasma, red and white blood cells, platelets, and blood grouping systems. - Explain the structure and essential functions of the lymphatic system and its role in fluid balance. - Analyze the human cardiac cycle, heart anatomy, and the generation of the heartbeat. - Differentiate between pulmonary, systemic, and portal circulatory pathways. - Explore common circulatory disorders and modern clinical insights into cardiovascular wellness. The course begins with foundational terminology and blood chemistry before guiding you through cardiac mechanics, blood vessel networks, and regulatory systems. You will consolidate your learning through written scenarios and conceptual review questions designed to test your comprehension. This course is designed for beginning biology students, pre-health majors, or anyone curious about how the human body functions, with no prior medical background required.
